Trademarks are inherently limited in scope. If I'm making widgets named FOO, and I've registered that trademark, I have no inherent right to FOO.com or @FOO or anything else that's completely general and may have nothing to do with widgets.

That?s why the Policy requires the trademark owner (the complainant) to prove bad faith and why the Policy offers domain name holders the opportunity to demonstrate that they have rights or legitimate interests in the domain name.
